Description
Technical Field
The embodiments of the present invention relate to the field of communications, and in particular, to a method, a network device, and a terminal device for wireless communication.
Background
Currently, the wireless communication standardization organization is discussing a delay shortening technology based on a Long Term Evolution (LTE) system, where the main optimization directions include: (1) a Transmission Time Interval (TTI) in the frame structure is shortened, for example, the TTI is shortened from 1ms to 0.5ms or even 1 Orthogonal Frequency Division Multiplexing (OFDM) symbol; (2) fast data transmission, which reduces the transmission time required by the user when uplink data arrives by adopting a mode of pre-allocating resources similar to Semi-Persistent Scheduling (SPS); (3) and optimizing the switching time delay, namely optimizing the time delay in the switching process, and mainly reducing the downlink synchronization time and the uplink synchronization time.
Wherein (2) the problem of data transmission delay when data arrives, especially uplink data arrives, which is faced at present, is mainly solved. According to the existing mechanism, when the terminal has no data transmission, the base station does not allocate uplink resources to the terminal. When a terminal needs data transmission, it first sends an uplink Scheduling Request (SR) to a base station, and then the base station allocates a fixed uplink Scheduling grant (UL grant) to the terminal, allowing the terminal to Report data to be transmitted in a memory, i.e. a Buffer Status Report (BSR), and then the base station allocates a certain resource to the terminal according to the data to be transmitted fed back from the BSR.
Currently, there are two schemes of dedicated resource allocation and UL grant pre-allocation based on a semi-persistent scheduling transmission mechanism for fast data transmission optimization, but the allocation and utilization efficiency of the UL grant in the two schemes is low, which causes waste of radio resources.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.
It should be understood that the technical solutions of the embodiments of the present invention can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a Long Term Evolution (LTE) System, a Frequency Division Duplex (FDD) System, a Time Division Duplex (TDD) System, a Universal Mobile Telecommunications System (UMTS), and a future 5G Communication System.
It should be understood that, in the embodiment of the present invention, a Terminal device (Terminal Equipment) may also be referred to as a user Equipment, a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), and the like, where the Terminal device may communicate with one or more core networks via a Radio Access Network (RAN), for example, the Terminal device may be a Mobile phone (or referred to as a "cellular" phone), a computer with a Mobile Terminal, and the like, for example, a Mobile device that may be portable, pocket, hand-held, computer-built, or vehicle-mounted, and a Terminal device in a future 5G Network or a Terminal device in a future evolved Public Land Mobile Network (PLMN) Network, and the like.
It should also be understood that, in the embodiment of the present invention, the network device may be a device for communicating with a terminal device, the network device may be a Base Station (BTS) in a GSM system or a CDMA system, a Base Station (NodeB) in a WCDMA system, an evolved Node B (eNB) in an LTE system, or an eNodeB, or the network device may be a relay Station, an access point, a vehicle-mounted device, a wearable device, and a network-side device in a future 5G network or a network device in a future evolved PLMN network, etc.
It should be noted that, in the embodiments of the present invention, "first", "second", and the like are only for convenience of description and do not constitute any limitation. For example, the first transmission period may be equal to the second transmission period, and the first transmission period may also be equal to the third transmission period.
Fig. 1 is a schematic flow diagram of a method of wireless communication according to an embodiment of the present invention, as shown in fig. 1, the method 100 comprising:
s110, a network device sends configuration information indicating that the terminal device carries out uplink data transmission according to a first transmission cycle to the terminal device;
and S120, the network device determines a second transmission period for the terminal device to perform uplink data transmission next time according to the data transmission state of the terminal device on the transmission resource corresponding to the first transmission period.
Therefore, according to the wireless communication method of the embodiment of the present invention, the network device can determine the transmission period of the next uplink data transmission performed by the terminal device according to the transmission state of the uplink data of the terminal device, thereby improving the allocation and utilization efficiency of the uplink transmission resource and avoiding the waste of the wireless resource.
It should be noted that, in the embodiment of the present invention, the transmission resource may refer to an uplink scheduling grant (UL grant) resource, and the terminal device may send a Buffer Status Report (BSR) or small packet data on the UL grant resource. The transmission period of the terminal device for uplink data transmission may be understood as a transmission period or a configuration period of the UL grant.
Optionally, in S110, the network device may send configuration information to the terminal device through a broadcast signaling or a dedicated signaling, and after receiving the configuration information, if there is a data packet to be transmitted, the terminal device queries a corresponding resource in a corresponding subframe according to an indication of the configuration information to send uplink data.
Optionally, in S120, when the network device receives the uplink data sent by the terminal device on the transmission resource corresponding to the first transmission period, the network device determines the second transmission period according to an adjustment parameter, where the second transmission period is smaller than the first transmission period and is greater than or equal to a first preset value.
That is, if the network device receives the uplink data sent by the terminal device on the transmission resource corresponding to the first transmission period, the network device may shorten a period for configuring the uplink transmission resource for the terminal device, and specifically, may perform adjustment of the resource configuration period according to an adjustment parameter specified by a standard or predetermined by the network device and the terminal device. For example, if the configuration period of the previous transmission resource is 40ms, and the network device receives uplink data sent by the terminal device on this transmission resource, the configuration period of the transmission resource may be shortened to 20 ms.
Alternatively, the minimum value of one transmission resource configuration period may be defined by a communication standard or configured by a network device. If the value determined according to the adjustment parameter is greater than the minimum value, the determined value is determined as a new configuration period, but if the value determined according to the adjustment parameter is less than or equal to the minimum value, the minimum value is determined as a new configuration period.
Optionally, in S120, when the network device does not receive the uplink data sent by the terminal device on the transmission resource corresponding to the first transmission period, the network device determines the second transmission period according to an adjustment parameter, where the second transmission period is greater than the first transmission period and is less than or equal to a second preset value.
That is, if the network device does not receive the uplink data sent by the terminal device on the transmission resource corresponding to the first transmission period, the network device may increase a configuration period for configuring the uplink transmission resource for the terminal device, and specifically, may perform adjustment of the resource configuration period according to an adjustment parameter specified by a standard or agreed in advance by the network device and the terminal device. For example, if the configuration period of the previous transmission resource is 40ms, and the network device does not receive the uplink data sent by the terminal device on this transmission resource, the configuration period of the transmission resource may be increased to 80 ms.
Alternatively, the maximum value of the configuration period of one transmission resource configuration may be defined by a communication standard or may be configured by the network device. If the value determined according to the adjustment parameter is greater than or equal to the maximum value, the maximum value is determined as a new configuration period, but if the value determined according to the adjustment parameter is less than the maximum value, the determined value is determined as a new configuration period.
Further, as shown in fig. 2, the method 100 further includes:
s130, when the network device receives the uplink data sent by the terminal device on the transmission resource corresponding to the second transmission period, determining a value smaller than the second transmission period as a third transmission period in which the terminal device performs uplink data transmission again.
That is, when the configuration period of the transmission resource increases, when the network device receives the uplink data sent by the terminal device, the configuration period of the transmission resource may be decreased. Specifically, the network device may determine, according to the adjustment parameter, a value smaller than the second transmission period, and determine the value smaller than the second transmission period as the third transmission period; or, the network device may directly adopt a mode of returning to the initial value, so as to reduce the configuration period of the transmission resource. For example, the first transmission period may be directly determined as the third transmission period.
In this embodiment of the present invention, optionally, the adjusting parameter may include an adjusting algorithm and/or an adjusting step size, and the network device may send a Radio Resource Control (RRC) message to the terminal device in a broadcast, multicast, or unicast manner, where the RRC message includes the adjusting parameter.
As an alternative example, the tuning algorithm may include a random selection algorithm, an exponential algorithm, or a linear algorithm, and the tuning algorithm may be identified by a specific bit, for example, the type of tuning algorithm may be identified by 2 bits, where "00" identifies the random selection algorithm, "01" identifies the exponential algorithm, and "10" identifies the linear algorithm. The adjustment step size can be identified by a specific format, for example, 20ms can be identified as 20fs or a System Frame Number (abbreviated as "SFN") + SubFrame Number (SubFrame) manner.
In the embodiment of the present invention, optionally, after the terminal device finishes transmitting the data packet on the transmission resource configured by the network device, there may still be data that is not sent. At this time, the terminal device may transmit the corresponding information to the network device, so that the network device performs corresponding resource allocation.
Specifically, the network device receives, on the transmission resource corresponding to the first transmission period, an uplink data packet sent by the terminal device, where the uplink data packet includes a Media Access Control (MAC) layer, where the MAC layer carries first indication information, and the first indication information is used to indicate whether the terminal device has data to be sent;
correspondingly, the network device determines the second transmission cycle and the transmission resource corresponding to the second transmission cycle according to the first indication information.
As an example, the MAC control element MAC CE part of the MAC layer carries the first indication information; or, the MAC header part of the MAC layer carries the first indication information; or the padding information part of the MAC layer carries the first indication information.
For example, a bit may be used to carry the first indication information, and when the value of the bit is 1, the terminal device is indicated to have a data packet that needs to be sent, and resources need to be reserved, and at this time, the network device may configure transmission resources for the terminal device by using a manner of dynamically configuring transmission resources in the prior art or a manner of configuring transmission resources at a fixed period. When the value of the bit is 0, it indicates that the terminal device does not have a data packet to be sent, and does not need to reserve resources, and at this time, the network device may configure transmission resources for the terminal device according to the original configuration cycle or increase the configuration cycle of the transmission resources.
Optionally, the network device receives, on the transmission resource corresponding to the first transmission cycle, an uplink data packet sent by the terminal device, and includes an MAC layer, where the MAC layer carries second indication information, and the second indication information is used to indicate that the terminal device has data to be sent and a size of the data to be sent, relative to the uplink data sent by the terminal device on the transmission resource corresponding to the first transmission cycle;
correspondingly, the network device determines the second transmission cycle and the transmission resource corresponding to the second transmission cycle according to the second indication information.
As an example, the MAC control element MAC CE part of the MAC layer carries the second indication information; or, the MAC header part of the MAC layer carries the second indication information; or the filling information part of the MAC layer carries the second indication information.
For example, one bit may be used to carry the second indication information, where a value of the bit is 1, to indicate that the terminal device has a data packet to be sent, and a size of the data packet to be sent is larger than a size of a data packet that has been sent before, and a resource block larger than a previously configured transmission resource block is needed to complete transmission of the data packet. When the value of the bit is 0, the terminal device is indicated to have a data packet to be sent, and the size of the data packet to be sent is smaller than or equal to the size of a data packet already sent before, and the data packet needs to be sent by the same resource block as before.
Therefore, according to the wireless communication method of the embodiment of the present invention, the network device can determine the transmission period of the next uplink data transmission performed by the terminal device according to the transmission state of the uplink data of the terminal device, thereby improving the allocation and utilization efficiency of the uplink transmission resource and avoiding the waste of the wireless resource.

and S220, the terminal equipment determines a second transmission period for next uplink data transmission according to the data transmission state on the transmission resource corresponding to the first transmission period.
Therefore, according to the wireless communication method of the embodiment of the present invention, the terminal device can determine the transmission period for the next uplink data transmission according to the uplink data transmission state of the terminal device, thereby improving the utilization efficiency of the uplink transmission resource and avoiding the waste of the wireless resource.
Optionally, S220 specifically is: and when the terminal sends uplink data to the network equipment on the transmission resource corresponding to the first transmission period, determining a second transmission period according to the adjustment parameter, wherein the second transmission period is smaller than the first transmission period and is greater than or equal to a first preset value.
